MECHANICAL AND ELECTRlCAL ALARM-CLOCK.

EPECZIFICATION 5 raising part of l'ietters Patent 330,317,837, dated h Iay 12, 1885.

Application filed February 18, 1885.

To aZZ whom it may concern/.-

Be it known that we, ISAAC S. MOSER and FRANCIS MAGEE, of the city, county, and State of New York, have invented a new and Improved Mechanical and Electrical Alarm- Olock, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved electrical attachment for alarm-clocks of the usual construction, where by, when the mechanical alarm is sounded, an electric circuit is closed and an electrical bell in the circuit is sounded until the circuit is broken.

The invention consists in the combination, with a mechanical alarm-clock having a spring for releasing the alarm mechanism, of tongues connected with electric circuit-wires, and of a circuit-closing piece on the end of the said spring, all as hereinafter fully described and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side View of our improved alarm-clock, the back plate being removed.

Fig. 2 is a cross-sectional view of the same.

Fig. 3 is a detail View ofthe alarm mechanism.

The alarm-clock A, provided with the usual clock and alarm mechanism, is provided with a gong, B, which is sounded by the alarmhammer G on the shaft I), having a projecting pin, E, adapted to engage with a pin or finger, I, on a spring, F, which is pressed outward in the usual manner, whereby theiinger I releases the pin E and shaft D, thus permitting the alarm-spring to operate the alarnr hammer C. All this is of the old well-known construction.

From a piece, G, of ebouite, hard rubber, or other insulating material, secured on the frame (No model.)

H of the clock-work, two metal tongues or contact-pieces, J, project, each being connected with an electric wire, (a, which are in the same circuit with a battery, K, and electric bell L.

On the free end of the spring F a piece, M, of ebouite, hard rubber, or other insulating material is held, and on the same a cross-piece, N, of metal is secured; or the cross-piece can be formed directly on the end of the spring.

\Vhen the spring F is pressed in the direction of the arrow at to release the mechanical alarm mechanism, the metal piece N comes in contact with the tongue Jand closes the electric circuit, whereby the electric bell L is sounded. The said bell is sounded until the circuit is broken, which is accomplished by turning the alarmhand, as thereby the spring F is permitted to move in the inverse direction of the arrow a. At the same time the mechanical alarm is also stopped.

The electric alarm-bell may be located any desired distance from the clock, but must be connected with the same by the wires a.

A number of electric bells in different rooms can be sounded from the clock A.

Having thus described our invention, we claim as new, and desire to secure by Letters Patent- The combination, with amechanical alarmclocl; having a spring, F, for releasing the alarm mechanism, of the insulating-piece G, the metal tongues J' on the same, the wires a, connected with the tongues J, the insulating-piece M on the spring F, and the circuitclosing piece N on the piece M, substantially as herein shown and described.
